Application filed June 27,

My invention relates to automatic weather Vstrips for doors and the like, and the objects of my invention are: first, to provide a dei/ice of this class which prevents all drafts under I doors or windows; second, to provide a de vice of this class which is automatically operated, but does not interfere with the action of the door or window; third, to provide a device of this class which is carried in a recess portion under the door or window when not in use; fourth, to provide a device ofthis class which automatically swings down from a recess in the lower portion of the door and closes the space between the under surface of the door and the threshold; fifth. to provide a device of this class which permits a wide space between the door and threshold so that the door will not stick during wet weather, yet will close the spaceeffectively; sixth, to provide a device of this class which does not operate until the door is almost closed, which at that point is tripped by a lever, thus `causing the weather strip to extend downwardly on the outer side and adjacent to the threshold; seventh, to provide a device of this class which can be readilyinstalled on the conventional door or easement window; and eighth, to provide a device of this class which is easy to apply, durable, efficient in its action, and whichwill not readily deteriorate or get out of order. f

With these and. other objects inview, as will appear hereinafter, my invention consists of certain novel :features of construction, combination and arrangement ofparts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, which form a part of this application, in which:

Figure l is a fragmentary elevational view of a door and door casing showing the door partially open and showing my device in relation therewith; Fig. 2 is an enlarged sectional view of my device through 2-2 of Fig. 3, showing by the solid line the door aj ar and indicating by dotted lines the closed 'position thereof; and Fig. 3 is a sectional View through 3-3 of Fig. 2, with parts and portions in elevation to facilitate the illustration.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The cover plate l, weather strip support 1927.` Serial No. 201 642.

plates 2 and 6, spacer 3, trip plunger Li, spring 5, weather strip 7, and plunger actuating means 8, constitute the principal `parts and portions of my automatic weather strip device. 1 l

The door D is provided with a grooved portion D1, which extends the wholelcngth of the under edge thereof. Thevouter projection formed by the groove, that is, the one on the outer side ofthe door, is beveled outwardly.' At the free end of the doorand set flush therewith is a cover plate 1, of which the lower portion thereof coversfthe end of the grooved portion D1 and the upper portion issecured to the door I) by means of screws.` The lower and outer sides la and 1b, respectively, of the cover plate l are fianged toward thepivoted end of the door and extend flush therewith. The outer, lower corner of the plate l and the adjoining flangedl portions are cut away, forming .a notched portion 1. A second plate 2, which serves as a lsupport for the weather strip, extends upwardly from the extreme edge of the flange l to the upper extremity of the grooved portionD1 and is adjacent to the edge of theiiange 1b, thereby completely filling the endthereof. The outer projection formed by the groove Dflis cut away so as to allow the plate 2 to meet the flanged portion l". The cover plate l and weather strip support plate 2are` heldy apart by a spacerB, which extends part way down froin'the `upper extremity of the grooved portionl),1 and to which are secured both the plates l and 2.

`It will be noted that the plate 2 may be inte end of'a spring 5, the other end of which rests against the inside projection of the door formed by the groove 131./ A lug 4 is secured in one side of the trip plunger 4 which extends throughy a slot 2d yof the weather strip support plate 2.

At the pivoted end of the door is secured a second weather strip support plate 6, which is set slightly in the edge of the door and secured theretov above Vthe grooved portion therein.y Between the two weather strip sup ports 2 and 6 is pivotally mounted a weather SFI ' strip 7. The weather strip 7 is a fiat strip,

preferably metallic, with an enlarged upper side- 7 positioned near the upper inside corner ot the groove D1. From the end of the enlarged side 7 extend lugs 7?, which extend Athrough holes in the support plates 2 and 6.

trip plunger noves back and forth,

the weather strip to rotate on'its pivotal axis.

'The threshold used in connection with this device is the conventional threshold T 7ith a weather baille T1.. '.lhetrip plunger l engagesthe plunger actuating means S, which is a projection extending up trom the threshold T adjacent to the doorjainb J, as shown best in Fig. 2 ot the drawings.

The operation of the device is as follows: lWhen the door'D is open, the weather strip is held within the grooved portion'l)1 by means oit the spring 5, which presses the trip plunger l outwardly and which in turn engages the weather strip, as shown best by the solid lines .in Fig. 2' of the drawings. The weather strip remains in its concealed'position until the door is brought to the position shown by the solid lines in Fig.V 2 ot the drawings. At this point the trip plunger Ll engages the projection 8 and causes the lug 4b thereol toturn the Weather strip on its pivotal axis as the doorinoves forwardly, thereby causing theweatherstrip to assume the position shown by the dotted lines in Fig. 2 of the drawings. l f

Though l have shown and described a particular construction, combination and arn rangement'ot.parts and portions, l do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention, the construction, combination and arrangement substantially as set iorthin the appended claims. Y

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: l

between.

l. ln a device of the class described, a door said groove in said door, a plunger reciprocally mountedin one of said weather strip supporting means, a lug' extending from said plunger through saidi weather strip supporting means, a weather strip pivotally mounted said weather strip supporting means, and a slotted lug at one end of said weather strip shiitable and .operatively coniected with said lug iii said plunger.

2. In a device of the class described, a door grooved at its lower edge, a weatherstripY supporting means secured over each end oi said groove insaid door, a. longitudinally shiiitable plunger reciprocally mounted in one oit' said weather strip supporting means, a lug extending from said plunger through said weather strip supporting means, a weatherr strip pivotally mounted between `said weather strip supporting means, a

slotted lug at one end ot' said weather strip operatively connected with said lug' in said plunger, resilient means for holding said plunger in itsl extendedl position, thereby holding said weather strip in its non-functioning position, and a projection on the jamb ot said door for forcing said plunger to its inward position against the action of `said resilient means.

ln ajdevice oi" the class described, a door grooved at its lower edge, afcover plate positioned over the free end ot said door andy over said groove, a second platepositioned within said groove and spaced apart from said cover plate,l a plunger -reciprocally mounted therein, a second plate secured to `the pivoted end of said door over said groove,

a weather strip pivotally mounted in said tirst and second mentioned plates, a slotted lug at the one end ot said weather strip, a

projection on said plunger adapted to opera- Y
